CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No. 62/525,046 filed Jun. 26, 2017, which is incorporated herein fully by reference in its entirety.

BACKGROUND

Shoulder-supported infant carriers are well known, and include a plethora of designs and styles that have been used for both front and back carriers. Such infant carriers offer “hands free” operation, allowing the wearer to carry the infant while performing other activities. Additional benefits include direct supervision of the child, an enhanced sense of security for the child, and the elimination of other larger and more cumbersome infant carriers such as strollers.

On-the-body carriers mandate that the harness straps must be sufficiently long to snugly fit a variety of different sizes. This leads to a significant disadvantage in that the excess straps can become quite an added encumbrance. Additionally, any time the position of the carrier is changed (e.g., wearing it on the front versus wearing it on the back) or a different caregiver wears the carrier (e.g., mom versus dad) the straps must be re-adjusted.

Accordingly, there remains a need for an infant carrier that eliminates the need for lengthy harness straps. Additionally, there is a need for an infant carrier that can be switched to multiple positions and/or multiple users without necessitating re-adjustment of the carrier. These needs and others are met by the present invention.

Throughout this application, various publications are referenced. The disclosures of these publications in their entireties are hereby incorporated by reference into this application in order to more fully describe the state of the art to which this pertains. The references disclosed are also individually and specifically incorporated by reference herein for the material contained in them that is discussed in the sentence in which the reference is relied upon. Nothing herein is to be construed as an admission that the present invention is not entitled to antedate such publication by virtue of prior invention. Further, the dates of publication provided herein may be different from the actual publication dates, which can require independent confirmation.

A. Definitions

As used in the specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a liner,” “a harness,” or “a car seat” includes mixtures of two or more such liners, harnesses, or car seats, and the like.

As used herein, the terms “optional” or “optionally” means that the subsequently described event or circumstance can or cannot occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.

As used herein, the term “dimensioned to support a child” means that the size and shape of the compartment are sufficient to bear the weight of a child. For example, the compartment can have a length of at least about 12 inches, at least about 14 inches, at least about 16 inches, at least about 18 inches, or at least about 20 inches, although other lengths are also envisioned. The compartment can have a width of at least about 7 inches, at least about 9 inches, at least about 11 inches, at least about 13 inches, at least about 15 inches, at least about 17 inches, or at least about 19 inches, although other widths are also envisioned. The compartment can have a thickness of at least about 0.1 inch, at least about 0.3 inches, at least about 0.5 inches, or at least about 0.7 inches, although other thicknesses are also envisioned. The compartment can be shaped like a sling, a wrap, a backpack, a pouch, or any other shape that allows for the child's spine to stay in its natural “C” shape.

As used herein, the term “dimensioned to support a child's head” means that the size and shape of the head support member are sufficient to bear the weight of a child's head. For example, the head support member can have a length of at least about 4 inches, at least about 5 inches, at least about 6 inches, or at least about 7 inches, although other lengths are also envisioned. The head support member can have a width of at least about 7 inches, at least about 8 inches, at least about 9 inches, at least about 10 inches, or at least about 11 inches, although other widths are also envisioned. The head support member can have a thickness of at least about 0.1 inch, at least about 0.3 inches, at least about 0.5 inches, or at least about 0.7 inches, although other thicknesses are also envisioned.

As used herein, the term “dimensioned to support a child's back” means that the size and shape of the back support member are sufficient to bear the weight of a child's back. For example, the back support member can have a length of at least about 8 inches, at least about 10 inches, at least about 12 inches, or at least about 14 inches, although other lengths are also envisioned. The back support member can have a width of at least about 7 inches, at least about 9 inches, at least about 11 inches, at least about 13 inches, at least about 15 inches, at least about 17 inches, or at least about 19 inches, although other widths are also envisioned. The back support member can have a thickness of at least about 0.1 inch, at least about 0.3 inches, at least about 0.5 inches, or at least about 0.7 inches, although other thicknesses are also envisioned.

As used herein, the term “dimensioned to support a child's bottom” means that the size and shape of the seat support member are sufficient to bear the weight of a child's bottom. For example, the seat support member can have a length of at least about 4 inches, at least about 5 inches, at least about 6 inches, or at least about 7 inches, although other lengths are also envisioned. The seat support member can have a width of at least about 7 inches, at least about 8 inches, at least about 9 inches, at least about 10 inches, or at least about 11 inches, although other widths are also envisioned. The seat support member can have a thickness of at least about 0.1 inch, at least about 0.3 inches, at least about 0.5 inches, or at least about 0.7 inches, although other thicknesses are also envisioned.

As used herein, the term “dimensioned to fit a wearer” means that the harness is of the right size and shape to secure onto the wearer, e.g., adult human.

As used herein, the term “retracted length” means the length of the elongated body in its relaxed state; that is, when no force is applied in the direction of elongation.

As used herein, the term “extended length” means the length of the elongated body under tension. For example, the elongated body may be fully elongated, at which point the elongated body cannot be elongated any further without breaking. Alternatively, the elongated body may be partially elongated such as, for example, 95% elongated, 90% elongated, 85% elongated, 80% elongated, 75% elongated, 70% elongated, 65% elongated, 60% elongated, or 55% elongated relative to the fully elongated body, although other percentages are also envisioned.

As used herein, the term “elastic ratio” means the quantitative relation between the length of a material within a component (e.g., a strap) and the extended length of the material within a component, when each is fully linear. The elastic ratio is equal to the extended length of the material divided by the retracted length of the material. For example, an elastic ratio of 2.0 indicates that the extended length of the material is twice as long as the retracted length of the material. Thus, it would be understood by one skilled in the art that the elastic ratio is a property of the material. Accordingly, a component comprising compartmentalized materials would have an elastic ratio for each material. Moreover, a component may be partially or wholly comprised of a blend of materials. In this instance, the blend is considered a composite material that would have its own elastic ratio.

As used herein, the term “stretch ratio” means the quantitative relation between the retracted length of a component (e.g., a strap) and the extended length of a component, when each is fully linear. The stretch ratio is equal to the extended length divided by the retracted length. For example, a stretch ratio of 2.0 indicates that the extended length is twice as long as the retracted length. Thus, it would be understood by one skilled in the art that the stretch ratio is a property of the component, which depends upon both the materials used in the component as well as the proportion of those materials. Generally, when the component comprises a single material, the stretch ratio of the component would be the same as the elastic ratio of the material.

As used herein, the term “component fraction” means the proportion of a component formed of a material. For example, a component fraction for rubber of 0.5 indicates that half of the component is formed from rubber. Typically, the stretchable portion (e.g., rubber) can be compartmentalized (e.g., half of the strap is rubber and half is formed of a non-stretchable material). In cases, however, wherein the stretchable and non-stretchable materials are integrated (e.g., the component comprises a blend of half elastic and half non-stretchable materials), it is less desirable to describe the component in terms of a component fraction; instead, it can be more desirable to describe the component in terms of the integrated material having its own elastic ratio.

As used herein, the term “adjustment member” means any component capable of affecting an alteration to achieve a desired fit. Examples of adjustment members include, but are not limited to, a buckle, a clasp, a fastener, a clamp, and a clip.

As used herein, the term “attachment member” means any component capable of reversibly attaching two components. Examples of attachment members include, but are not limited to, rings, clips, carabiners, swivel-hooks, snaps, snap-hooks, bulldog clips, trigger hooks, and hooks.

As used herein, the term “reversibly attached” means joined together in a manner capable of being detached without destroying the material. For example, a harness may be reversibly attached to a compartment, whereby the harness and the compartment are securely joined together, thereby forming a carrier, but whereby the harness can be detached from the compartment, thereby forming two distinct components, if desired. It would be understood by one skilled in the art that the harness could similarly be re-attached to the compartment when desired. A component can be reversibly attached by, for example, an attachment member.

As used herein, the term “fixedly attached” means joined together in a manner incapable of being detached without destroying the material, even if detachment is technically possible. For example, a harness may be fixedly attached to a compartment by sewing, glue, or a staple. Removal of the seam or staple would likely result in fraying or tearing of the components.

As used herein, the term “integral” means formed as a single unit. Thus, it would be understood by one skilled in the art that two distinct components can be joined together, thereby resulting in a single unit. For example, a compartment may include a head support member and a back support member formed integrally as a single unit, whereby the precise location at which one member ends and the next begins is ambiguous. Conversely, a compartment may include a head support member and a back support member joined together by, for example, sewing, whereby the each component is separated by a seam, or the like, and thus remains distinguishable as two distinct components.

As used herein, the term “adapted to connect” means made suitable for bringing together. For example, the first end of a strap can be adapted to connect to the head support member by a carabiner, although other means of connection are also envisioned.

B. Carriers

In one aspect, disclosed are carriers comprising: (a) a compartment dimensioned to support a child, wherein the compartment is attached to (b) a harness dimensioned to fit a wearer, wherein the harness comprises a pair of straps, wherein each strap comprises an elongated body having a first end, a second end, a retracted length, and an extended length, and wherein each strap has a stretch ratio of from about 1.2 to about 4.0.

In one aspect, disclosed are carriers comprising: (a) a compartment dimensioned to support a child, wherein the compartment is attached to (b) a harness dimensioned to fit a wearer, wherein the harness comprises: (i) a pair of straps, wherein each strap comprises an elongated body having a first end, a second end, a retracted length, and an extended length, and wherein each strap has a stretch ratio of between 1.2 and 4.0; and (ii) a strap configured to encircle a wearer's waist, wherein the strap comprises an elongated body having a first end, a second end, a retracted length, and an extended length.

In one aspect, disclosed are carriers comprising: (a) a compartment dimensioned to support a child, wherein the compartment is attached to (b) a harness dimensioned to fit a wearer, wherein the harness comprises a pair of straps, wherein each strap comprises an elongated body having a first end, a second end, a retracted length, and an extended length, and wherein each strap has an elastic ratio of greater than 1.0.

Referring to FIG. 3A and FIG. 3B, for example, the carrier can comprise a compartment 312 and a harness. As shown here, the compartment comprises head support member 301 having top edge 302, first body support member 303 (i.e., a back support member), and second body support member 304. First body support member 303 and second body support member 304 together comprise seat support member 305. Head support member 301 is integral with first body support member 303. As shown here, the harness comprises a pair of straps 306 configured to be worn by a wearer and strap 307 (i.e., a waist strap) configured to encircle a wearer's waist. Each of straps 306 and 307 are sufficiently elastic to extend and retract along their lengths, eliminating the need to adjust the carrier to the position and/or wearer. As shown here, head support member 301 is reversibly attached to second body support member 304 via attachment members 308. Exemplary attachment members include, but are not limited to, rings, clips, carabiners, swivel-hooks, snaps, snap-hooks, bulldog clips, trigger hooks, and hooks. Alternatively, head support member 301 can be reversibly attached to second body support member 304 via a pair of straps having an attachment member thereon or via a single strap having a first attachment member and a second attachment member directly connected to either the head support member or the second body support member, wherein the second attachment member is configured for engagement with the first attachment member. As shown here, each strap 306 is connected to top edge 302 by, for example, a seam. Alternatively, each strap can be reversibly attached to the head support member via an attachment member. In various aspects, the adjacent end of the straps (not shown) may comprise an attachment member configured for engagement with attachment members 309. In this way, each strap can be extended over a wearer's shoulder and around a wearer's torso and then joined to attachment member 309. First body support member 303 is reversibly attached to second body support member 304 via attachment members 310. As shown here, attachment members 310 comprise snaps, although other attachment members such as, for example, rings, clips, carabiners, swivel-hooks, snaps, snap-hooks, bulldog clips, trigger hooks, and hooks are also envisioned. As shown here, one end of strap 307 comprises attachment member 311, which is configured for engagement with a second attachment member (not shown) on the opposing end of strap 307. Alternative means of connecting strap 307 are also envisioned. For example, each end of strap 307 can reversibly attach to the compartment. In a further example, each end of strap 307 may not comprise an attachment member. Rather, each end could merely be extended around a wearer's waist and securely fastened.

Referring to FIG. 4A-C, for example, the carrier can comprise a compartment and a harness. As shown here, the compartment comprises head support member 401, first body support member 403, and second body support member 404. Head support member 401 in combination with second body support member 404 have a top edge 402, which defines a hole. Head support member 401 is integral with first body support member 403. As shown here, the harness comprises a pair of sufficiently elastic straps 405 configured to be worn by a wearer, wherein each strap 405 is inserted through padded member 406, which may provide additional comfort and/or support to a wearer's shoulders. As shown here, each side edge of first body support member 403 comprises a first pair attachment member reversibly attached to a second attachment member located on each side edge of second body support member 404 (collectively shown as 409). Exemplary attachment members include, but are not limited to, rings, clips, carabiners, swivel-hooks, snaps, snap-hooks, bulldog clips, trigger hooks, and hooks. Alternatively, first body support member 403 can be reversibly attached to second body support member 404 via a pair of straps having an attachment member thereon or via a single strap having a first attachment member and a second attachment member directly connected to either the first body support member or the second body support member, wherein the second attachment member is configured for engagement with the first attachment member. As shown here, each side edge of first body support member 403 comprises a third attachment member reversibly attached to a fourth attachment member located on each side edge of second body support member 404 (collectively shown as 408). Each attachment member can be on a strap, as shown here, or can be directly connected to the support member, or any combination thereof. As shown here, each strap 405 is connected to second body support member 404 by, for example, a seam. Alternatively, each strap can be reversibly attached to the second body support member via an attachment member. In various aspects, the adjacent end of the straps (not shown) may comprise an attachment member configured for engagement with a pair of attachment members 412 and 413. In this way, each strap can be extended over a wearer's shoulder and around a wearer's torso and then joined to attachment members 412 and 413. Finally, as shown here, first body support member 403 may comprise a pair of attachment members 407, which can be reversibly attached to a pair of attachment members on a strap configured to encircle a wearer's waist (not shown).

Referring to FIG. 4A, for example, the carrier can comprise a compartment and a harness, wherein the compartment comprises transition region 410 within second body support member 404. As shown here, transition region 410 is configured to allow second support member 404 to be selectively moved between an unfolded position and folded position (folded position is shown in FIG. 4A). The folded position may be secured by snap 411, although over attachment means are also envisioned.

Referring to FIGS. 4B and 4C, for example, the carrier can comprise a compartment and a harness, wherein the compartment comprises transition region 415 defined between first support member 403 and head support member 401. As shown here, transition region 415 is configured to allow head support member 401 to be selectively moved between an unfolded position (FIG. 4B) and a folded position (FIG. 4C). The folded position may be secured by hook-and-loops on strips 414, although other attachment means are also envisioned.

In a further aspect, the compartment and the harness are integral. Thus, in various aspects, the compartment and the harness together form a single unit. In a still further aspect, the compartment and the harness are not integral. Thus, in various aspects, the compartment and the harness are two separate units, joined together by, for example, a seam, a snap, a button and buttonhole, or a clip.

In a further aspect, the carrier is dimensioned so that in operable condition the compartment is on the front of the wearer. In a still further aspect, the carrier is dimensioned so that in operable condition the compartment is on the front of the wearer and the child faces the wearer. In yet a further aspect, the carrier is dimensioned so that in operable condition the compartment is on the front of the wearer and the child opposes the wearer.

In a further aspect, the carrier is dimensioned so that in operable condition the compartment is on the back of the wearer. In a still further aspect, the carrier is dimensioned so that in operable condition the compartment is on the back of the wearer and the child faces the wearer. In yet a further aspect, the carrier is dimensioned so that in operable condition the compartment is on the back of the wearer and the child opposes the wearer.

1. Compartments

In one aspect, the disclosed carrier comprises a compartment dimensioned to support a child.

In one aspect, the disclosed carrier comprises a compartment dimensioned to support a child, wherein the compartment has a top edge defining an opening. In a further aspect, in operation, the compartment is so dimensioned as to allow a child's face to extend out of the opening. In yet a further aspect, in operation, the compartment is so dimensioned as to allow a child's head to extend out of the opening.

In a further aspect, the compartment is not dimensioned to support a child in a car seat. For example, a compartment dimensioned to support a child in a car seat may comprise a surface having an inner edge defining a hole, whereby a car seat strap can be manipulated through. Thus, in various aspects, the disclosed compartment comprises a surface lacking an inner edge defining a hole dimensioned to accept a seatbelt buckle. Alternatively, the compartment comprises a surface having exactly two inner edges, wherein each edge defines a hole, and wherein each hole is dimensioned to allow a child's leg to be insertable through the opening. In another example, a compartment dimensioned to support a child in a car seat may be shaped so as to allow a car seat strap to be easily manipulated around the compartment. Thus, in various aspects, the disclosed compartment is shaped such that a car seat strap cannot easily be accessed.

In various aspects, the compartment may resemble a pouch in which a child can be retained in an upright position with their legs maintained inside the pouch. This may be especially beneficial for young infants who are most comfortable curled up akin to being inside their mother's womb. Moreover, this position may also help a child to stay warm while being transported about.

In a further aspect, the compartment has two inner edges, wherein each edge defines a hole. In a still further aspect, in operation, the compartment is so dimensioned as to allow a child's legs to extend of the holes.

In various aspects, the compartment may resemble a pouch in which a child can be retained in an upright position with their legs extended out of the pouch.

In a further aspect, the compartment has a width of from about 7 inches to about 20 inches. In a still further aspect, the compartment has a width of from about 7 inches to about 18 inches. In yet a further aspect, the compartment has a width of from about 7 inches to about 16 inches. In an even further aspect, the compartment has a width of from about 7 inches to about 14 inches. In a still further aspect, the compartment has a width of from about 7 inches to about 12 inches. In yet a further aspect, the compartment has a width of from about 7 inches to about 10 inches. In an even further aspect, the compartment has a width of from about 10 inches to about 20 inches. In a still further aspect, the compartment has a width of from about 12 inches to about 20 inches. In yet a further aspect, the compartment has a width of from about 14 inches to about 20 inches. In an even further aspect, the compartment has a width of from about 16 inches to about 20 inches.

In a further aspect, the compartment has a length of from about 12 inches to about 20 inches. In a still further aspect, the compartment has a length of from about 12 inches to about 18 inches. In yet a further aspect, the compartment has a length of from about 12 inches to about 16 inches. In an even further aspect, the compartment has a length of from about 12 inches to about 14 inches. In a still further aspect, the compartment has a length of from about 14 inches to about 20 inches. In yet a further aspect, the compartment has a length of from about 16 inches to about 20 inches. In an even further aspect, the compartment has a length of from about 18 inches to about 20 inches.

In a further aspect, the compartment has a weight capacity of about 50 lbs. In a still further aspect, the compartment has a weight capacity of about 45 lbs. In yet a further aspect, the compartment has a weight capacity of about 40 lbs. In an even further aspect, the compartment has a weight capacity of about 35 lbs. In a still further aspect, the compartment has a weight capacity of about 30 lbs. In yet a further aspect, the compartment has a weight capacity of about 25 lbs.

In a further aspect, the compartment comprises a stretchable material. Thus, in various aspects, the compartment comprises a material with a stretch ratio of more than about 1.2. In a still further aspect, the compartment comprises a material with a stretch ratio of more than about 1.5, more than about 2.0, more than about 2.5, more than about 3.0, or more than about 3.5. In various further aspects, the compartment comprises a material with a stretch ratio of less than about 1.2. In yet a further aspect, the compartment comprises a material with a stretch ratio of less than about 1.0, less than about 0.8, less than about 0.6, less than about 0.4, less than about 0.2, or less than about 0.1. In an even further aspect, the compartment comprises a non-stretchable material.

In a further aspect, the compartment has a top edge defining an opening and wherein, in operation, the compartment is so dimensioned as to allow a child's head to extend out of the opening.

In a further aspect, the compartment further comprises a transition region defined between the back support member and the head support member, wherein the transition region is configured to allow the head support member to be selectively moved between an unfolded position and a folded position where at the head support member is folded down into an overlapping relation to the back support member.

a. Head Support Members

In a further aspect, the compartment comprises a head support member dimensioned to support a child's head. For example, the head support member can support the back and/or sides of a child's head. Young infants do not have enough strength in their necks to hold their heads up to keep their airways open. Rather, their heads tend to flop sideways, forward, or even backward. Placing support behind and alongside the infant's head can prevent this movement and improve head positioning. Thus, in various aspects, the head support member, in operation, is so dimensioned as to support the back of a child's head. In a further aspect, the head support member, in operation, is so dimensioned as to support the sides of a child's head. In a still further aspect, the head support member, in operation, is so dimensioned as to support the back and sides of a child's head.

The head support member can be formed of any suitable material that provides good cushioning. Exemplary materials include, but are not limited to, waterproof nylon, flannel, and elastic fabrics such as spandex or cotton-spandex blends.

The head support member can optionally be filled with a compressible, resilient material. Exemplary fillers include, but are not limited to, polyester fiberfill, down feathers, memory foam, and polystyrene pellets.
